I've seen in a few threads the mention of torque rods needing to be over length and not glued all the way to allow them to bend when used with top hinged ailerons, or not being able to use them at all.
this is because the center part of the aileron is now moving in and out.
I've always done this so I'll share this simple tip.

simply drill and glue a snake inner ( matching your torque rod ) inside the aileron. now fit your torque rod, as you move it up and down the snake allows the peg to slide in and out.
on a glider I've just done, the rod is actually right on the bottom of the wing and the snake glued just under the glass skin surface, this is where there is most movement and it works just fine.

to save space i also rub wax all over the torque rod, then cut a V into the wing, the torque rod is placed in and epoxy poured in over the top, to make the skin clean i add some tape to the top while it dries. when dry knock the rod and it'll break free of the glue. no slop perfect installations.
